📝 Walkthrough

Walkthrough

The change adds Material and Material Mono themes, configurable appearance settings, display-shape and inset support, reusable widgets, and grid navigation. Applications adopt themed widgets and revised layouts. Input handling adds focus-navigation keys and trackball key mode. Status-bar behavior changes, several ESP-IDF LVGL wrappers are removed, and the LVGL dependency changes from 9.3.0 to 9.4.0.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to b088c

Existing favourites will not appear after an upgrade, and selecting an unchanged theme can prompt an unnecessary Apply action. Custom input-group navigation may also break. Address these issues before merging.

🟡 Minor · Remove each theme’s resolution callback before freeing it. · theme.cpp:97-110

Modules/lvgl-module/source/theme.cpp:97-110
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Remove each theme’s resolution callback before freeing it.

When a new display selects the other theme, lvgl_theme_init_for_display() deinitializes the current theme. The generated callback remains registered on its displays with the freed theme as user data. LVGL 9.4 emits LV_EVENT_RESOLUTION_CHANGED when rotation changes, so rotating one of those displays calls the stale callback, which passes &theme->config to the old initializer. That can read freed configuration. Remove the old callback from every display before freeing theme_def.
